Hi,
for writing OSM data there is no call to geometry.transform
you can patch the file OSM.js
createXML: {
'point': function(point) {
var id = null;
var geometry = point.geometry ? point.geometry : point;
//at line 349 add this 5 lines
if (this.externalProjection && this.internalProjection) {
geometry = geometry.clone();
geometry.transform(this.internalProjection,
this.externalProjection);
}
//
var already_exists = false; // We don't return anything if the
node
and the transformation for writing works.
What i don't understand, that an externalProjection given in the options is
used instead of
// OSM coordinates are always in longlat WGS84
this.externalProjection = new OpenLayers.Projection("EPSG:4326");
as set in the initialize function, what should overwrite the options value.
With the patch one can create OSM data in different projection than
EPSG:4326.

Betreff: Re: [OpenLayers-Users] Write feature in another projection
Hi Stephane,
No, a tried the two ways to be sure and I paste the wrong one.
Anyway OpenLayer.Format.OSM does not seem to handle
'internal/externalProjection'. Now I'm happy with:
var x = new OpenLayers.Format.WKT({
'internalProjection': new
OpenLayers.Projection("EPSG:900913"),
'externalProjection': new
OpenLayers.Projection("EPSG:4326")
});
